In subtropical environments lodging occurs at all stages of the oat plant development, particularly after panicle extrusion, causing severe yield reduction. This study aimed to identify morphological, chemical, and anatomical characteristics stem associated with resistance on oats, which may be used select resistant genotypes. A set genotypes diverse response were grown in nine environments, co...

in order to locate the qtls for plant height, peduncle length, and heading date, a set of 107 wheat doubled haploid (dh) lines derived from the cross fukuho-komugi× oligoculm was grown during the growing seasons of 2004 and 2005. a total of 36 qtls were identified based on composite interval mapping (cim) approach. all detected plant height qtl’s were stable over the two years. qtls located nea...

effects of different paclobutrazol concentrations (0, 250, 350 and 450 mgl-1) and plantlet density (80, 100 and 120 plantlet/m2) on minituber production per plantlet in potato cultivar ‘sante’ were investigated in a factorial experiment based upon a randomized complete block design of 4 replications. paclobutrazol (cultar with 250 g/l of active ingredient) was used as foliar application at earl...

Adaptive evolution of phenotypic plasticity requires that plastic genotypes have the highest global fitness. We studied selection by spatial heterogeneity of interspecific competition and flooding, and by temporal heterogeneity of flooding on morphological plasticity of 52 genotypes of the clonal shore plant Ranunculus reptans. Competition reduced clone size, rosette size, leaf length and stolo...

in order to evaluate the morphological characteristics and lodging related traits and carbohydrate content of culm and carbohydrate remobilization in traditional and improved rice cultivars, a field experiment was laid out in randomized complete block design with three replications at rice research institute of iran )rasht( in 2012 and 2013. rice genotypes included three native rice cultivars (...

Opportunities exist for replacing reduced height (Rht) genes Rht-B1b and Rht-D1b with alternative dwarfing genes, such as the gibberellin-responsive gene Rht12, for bread wheat improvement. However, a comprehensive understanding of the effects and mode of action of Rht12 is lacking. In the present study, the effects of Rht12 were characterized by analyzing its effects on seeding vigour, seedlin...

Sorghum is a grain plant that source of food, biofuel and feed, which can be produced using the techniques ratoon cultivation. The objective this study to assess nutrition content, performance four sorghum genotypes vegetative characteristics ratoon. research was carried out from December 2020 July 2021 at Ciawi Research Garden, Livestock Institute. employed treatments (genotype) three replicat...

Despite the economic significance of periwinkle [Catharanthus roseus (L.) G. Don] existence genetic variation in traits have been largely unexplored and very little attempt has done to improve its genetics for ornamental prospective. An experiment was conducted at research farm Punjab Agricultural University, Ludhiana, during 2019 2021 using 6 inbred lines develop 30 F1 populations full-diallel...

One hundred and seven half-sib families of Pinus pinaster planted at four sites in Galicia (NW Spain) were evaluated at age 8 for growth (height, diameter, volume and mean internode length), stem form (straightness, leaning, forking) and branching characteristics (branch diameter, angle and number and total number of whorls). The analyzed half-sib families were obtained from first-generation pl...
